WEIGHT-PAN FOR BALANCES.

SPECIFICATION forming part of Letters Patent No. 480,027, dated August2, 1892. Application filed January 26, 1892. Serial No. 419,345- (Nomodel.)

To all whom it may concern:

Be it known that I, ROBERT E. MGCLEL- LAND, a citizen of the UnitedStates, residing at \Villiamsville, in the county of Sangamon andStateot Illinois, have invented certain new and useful Improvements inDruggistsScales; and I do hereby declare the following to be a full,clear, and exact description of the invention, which will enable othersskilled in the art to which it appertains to make and use the same.

My present invention relates to various new and useful improvements indruggists scales, and more particularly to an improved mechanism forautomatically depositing any desired weight or weights in the scale-panand for automatically removing said weight or weights when desired.

The principal novelties in my present invention consist of one moreseries of cups or receptacles pivotally mounted on the scalepan andconnected together. It is preferable to make use of two or more seriesof such cups or receptacles arranged parallel with each other andnormally held in an inclined position. Pivoted on the outside of thescalebeam, so as to face the mouths of said cups or receptacles, arecorresponding cups, which receive and contain the necessary weights.These latter cups or receptacles are also normally inclined and areindependent of each other. Each of these latter cups or receptacles isprovided with a lever adapted to be pressed by the finger, which bearsunder the cup or receptacle and by which the angle or inclination of thelatter may be changed, so that a desired weight may be rolled out of themouth of the cup or receptacle into the adjacent eup on the scale-pan.The cups or receptacles on the scale-pan are also adapted to besimultaneously operated, so that their angle or inclination will bechanged by means of a single lever adapted to be operated by the finger.By changing the angle or inclination of these cups on the scale-pan theweights which may be therein will be allowed to roll outof the mouththereof into the proper cup at the side.

For a better comprehension of my present invention attention is directedto the accompanying drawings, forming a part of this specification, andin which Figure 1 is a top view of my device, showing aportion of thecasing broken away. Fig. 2 is an end elevation of Fig. l, and Fig. 3 isan enlarged section of a pair of cups or receptacles.

In all of the several views like parts are designated by identicalletters of reference.

My device consists, first, of a hollow rectangular casing A, supportinga standard 13, upon which is mounted an ordinary scalebeam 0, carryingan index-finger D and two pans E and F for holding the weights and thearticle to be weighed, respectively. A segmentG, suitably graduated, isrigidly mounted upon one side of the standard 15. This segment isadapted to serve the ordinary pur pose of such devicesnamely, to quicklyand accurately ascertain when the balance-beam is exactly horizontal orwhen the pans exactly counterbalance. Mounted within this scalepan E aretwo sets or series of cups or receptacles H II of a general oblong shapeand with beveled outside extremities. These cups are preferably open atthe tops and outer extremities, as shown in the drawings. The inner endsof the cups of each series are secured to a metallic supporting-piece I,which is bent at each side, as shown, and which bears within the side ofthe scale-pan E at a point directly in line with the mouths of said cupsor receptacles.

J J are other cups or receptacles similar in every respect to the cups HH, with the exception that these are independently mounted upon andsupported by a suitable shaft or axle K, passing beneath the outer ends.They normally assume the posi ion illustrated in Fig. 2.

L L Lare levers independent of each other and mounted on a shaft Mwithin the casing A. Each lever is provided at its outer end withfinger-piece N, upon which is indicated the proper weight. These leversextend underneath the cups or receptacles .T J, one for each, and areprovided at their inner edge with a vertical extension 0, which bearsupon a suitable cup or receptacle J J. By pressing downward on any leverits inner end will be elevated, so that the angle or inclination of thecup or receptacle will be changed and the weight contained therein willroll out into the cups or receptacles II on the scale-pan E.

P is another lever, preferably placed in the center of the casing A, andis provided with branch arms Q Q at its inner end. This lever P ispivotally mounted upon the shaft M in a manner similar to the levers L Land is provided with a finger-piece similar to the pieces N N.

Each of the branch arms Q Q is provided at its inner extremity with avertical extension R, (similar to the extension 0,) which is adapted tobear under any one of the cups or receptacles 0. Then in a normalposition, the extensions R do not touch the cups 01' receptacles H H,but remain some distance therefrom to allow the scale-beam O tooscillate up or down without being impeded in any way.

Upon pressing the finger-piece of the lever P the vertical extension atthe end of each branch arm will be elevated so as to come in contactwith the cups or receptacles H H, which are connected together, and bythis means the angle or inclination thereof will be changed, so that anyweights which may be within the cups or receptacles H H will roll outthereof into the adjacent cups or receptacles K K.

The weights which I prefer to employ are preferably of metal anddisk-shaped, so as to readily roll down an inclined plane. Thedifferences in weight of the weights are secured by differentthicknesses with a uniform diameter.

By constructing the weights of a disk shape the specific weights canbeidentical by raised,

sunken, or colored numbers upon the flat faces, which would beimpossible were the weights spherical or without flattened faces.

The operation of my device is substantially as follows: The article tobe Weighed being deposited within the pan F, the operator proceeds todeposit suitable weights upon the scale-pan E by depressing the leversL, which will tilt the cup or receptacle K, as shown in Fig. 3, (dottedlines,) and allow the weight to roll into the adjacent receptacle H uponthe scale-pan. When the article to be weighed is counterbalanced by theweights, they are returned to the cups K K by depressing the lever P,which will elevate the inner extremities of the cups or receptacles H H,as shown in dotted lines of Fig. 3, and allow the weight to rollback tothe cups K K.

Having now described my invention, what I claim as new therein, anddesire to secure by Letters Patent, is as follows:

An improved device for weighing, consisting of a scale-pan provided withtwo or more tilting cups or receptacles arranged in series, a suitablefinger-lever for tilting all of the receptacles within a series, two ormore tilting weight-holding cups or receptacles, and an independentfinger-lever for tilting each of said cups or receptacles, incombination with two or more disk-shaped weights, all combinedsubstantially as described.
